It's my project situation now.
MainActivity is LAUNCHER
SplashActivity called MainActivity onCreate()
When I think about it, it looks like there is no problem.
but after app starting,
The MainActivity screen is briefly visible before SplashActivity call.
Surprisingly, I did not see it on other devices, only galaxy s8.
Of course, I know it is not a general structure. But I can not understand it because I have been working normally.
white color is cold start style and splashActivity.
red color is mainActivity
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// some getIntent code
startActivityForResult(new Intent(this, SplashActivity.class), RESULTCODE_);
setInitLayout();
}
manifest
<activity android:name=".MainActivity"
android:screenOrientation="portrait"
android:theme="#style/SplashTheme" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".SplashActivity"
android:configChanges="orientation|keyboard|keyboardHidden|screenSize"
android:screenOrientation="portrait"
android:theme="#style/SplashTheme" >
</activity>
minSdkVersion 21
targetSdkVersion 28
If you use style with android:windowBackground for splash activity, don't call setContentView(). Thats all!
It is not a good idea to use a splash screen that way . This should be strictly avoided.
With this approach you may also lead the problem of blank white page appears during splash launching and this what exactly happened to you !
i advice you to read this article and try to make your splash screen in the right way to avoid such behavior !
You have placed MainActivity class to be the launcher activity in your manifest. I am assuming that your splashscreen activity is called SplashActivity. If you want it to be shown before as the SplashScreen and then MainActivity to come later on, change your manifest code to be:
<activity android:name=".SplashActivity"
android:screenOrientation="portrait"
android:theme="#style/SplashTheme" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MainActivity"
android:configChanges="orientation|keyboard|keyboardHidden|screenSize"
android:screenOrientation="portrait"
android:theme="#style/SplashTheme" >
</activity>
<activity android:name=".IntroActivity"
android:configChanges="orientation|keyboard|keyboardHidden|screenSize"
android:screenOrientation="portrait"
android:theme="#style/SplashTheme" >
</activity>
Then create your SplashActivity as suggested by Ismail in the link that he has provided
simply add handler for limited seconds of time and finish current activity
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
//actvity transaction
}
},3000);
Use this thread code for splash activity it will better work -
public class SplashActivity extends AppCompatActivity {
private static int SPLASH_TIME_OUT = 3000;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
Thread thread = new Thread() {
public void run(){
try{
sleep(3000);
}catch (InterruptedException e){
e.printStackTrace();
}finally {
Intent mainAct=new Intent(SplashActivity.this, MainActivity.class);
startActivity(mainAct);
finish();
}
}
};
thread.start();
}
#Override
protected void onDestroy() {
super.onDestroy();
}
}
and your manifest class will be look like this :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.example.diskapp">
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="#drawable/logo"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme"
tools:ignore="AllowBackup,GoogleAppIndexingWarning">
<activity android:name=".Activities.SplashActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".Activities.MainActivity" />
</application>
</manifest>
Use this thread code for splash activity. It will better work :
public class SplashActivity extends AppCompatActivity {
private static int SPLASH_TIME_OUT = 3000;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
Thread thread = new Thread() {
public void run(){
try{
sleep(3000);
}catch (InterruptedException e){
e.printStackTrace();
}finally {
Intent mainAct=new Intent(SplashActivity.this, MainActivity.class);
startActivity(mainAct);
finish();
}
}
};
thread.start();
}
#Override
protected void onDestroy() {
super.onDestroy();
}
}

I was having a play with Android Studio to create a birthday card and have come to a slight problem with the audio file playing before MainActivity is even on screen. The audio file plays while the splash screen is still on the screen.
I have two Java files:
MainActivity.class
package com.example.android.happybirthday;
import android.media.MediaPlayer;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
MediaPlayer mySoundfile;
#Override
protected void onPause() {
super.onPause();
mySoundfile.release();
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mySoundfile = MediaPlayer.create(this, R.raw.music);
mySoundfile.setLooping(true);
mySoundfile.setVolume(100, 100);
mySoundfile.seekTo(0);
mySoundfile.start();
}
}
and Splash.class
package com.example.android.happybirthday;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
public class Splash extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash_screen);
Thread mythread = new Thread() {
#Override
public void run() {
try {
sleep(3000); // 3 second delay for cold start
Intent startMainApp = new Intent(getApplicationContext(), MainActivity.class); // initiate MainActivity
startActivity(startMainApp); // open MainActivity
finish(); // close this activity
} catch (InterruptedException e) {
e.printStackTrace();
}
}
};
mythread.start();
}
}
This is the AndroidManifest.xml file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android.happybirthday">
<application

</intent-filter>
</activity>
</application>
</manifest>
Could you kindly give some support?
Thanks :)
Thanks #Sergey and #You Kim, I managed to get it done via adding a delay in onStart within the MainActivity.class
you need to run the media player when the activity is started, not on the create.
try running media player on onStart() or onResume().
Called when activity resume is complete
protected void onPostResume()
is it possible to get a login activity in between splash and main activity in android studio.`it should be after splash activity and before main.how to get it.
<?xml version="1.0" encoding="utf-8"?>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme" >
<activity
android:name=".Splash"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".Register"
android:label="#string/title_activity_register"
android:theme="#style/AppTheme.NoActionBar"/>
<activity android:name=".MainActivity"
android:theme="#style/AppTheme.NoActionBar"/>
</application>
You may change your manifest like this
<application
android:allowBackup="true"
android:icon="#drawable/icon"
android:label="#string/app_name"
android:logo="#drawable/icon"
>
<activity
android:name=".SplashActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".LoginPage"></activity>
<activity android:name=".MainPage"></activity>
</application>
and make sure your intents are appropriare in order
When you call splash activity, inside splash activity just call loginactivity and if you are on login activity, on press of the button, call mainactivity. That's it.
public class SplashActivity extends Activity {
private final int STR_SPLASH_TIME = 3000;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
startSplashTimer();
}
private void startSplashTimer() {
try {
Timer timer = new Timer();
timer.schedule(new TimerTask() {
#Override
public void run() {
Intent intent = new Intent(SplashActivity.this, LoginActivity.class);
startActivity(intent);
finish();
}
}, STR_SPLASH_TIME);
} catch (Exception e) {
e.printStackTrace();
}
}
From SplashActivity, it will be going to the LoginActivity, when this happened after that onclick of the button call MainActivity.
So your flow should be like this,
SplashActivity --> LoginActivity --> MainActivity
I've answered a similar question two or three weeks ago. Find the answer here.
However, in my opinion, creating an activity just for showing a splash is not so good. Essentially, your app should have as few activities as it can. Activities are, with no doubts, the main and heaviest component for an app. So, for just showing a splash for you may want to show that splash in your LoginActivity until further resources are loaded. Once all are loaded, you can hide that splash and show log-in form.
Do something like this:
SplashActivity.java
public class SplashActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.chat_activity);
...
if(!alreadyLoggedIn()) {
Intent intent = new Intent(SplashActivity.this, LoginActivity.class);
startActivity(intent);
} else {
Intent intent = new Intent(SplashActivity.this, MainActivity.class);
startActivity(intent);
}
}
}
LoginActivity.java
public class LoginActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.chat_activity);
if(loginSuccessful()) {
Intent intent = new Intent(LoginActivity.this, MainActivity.class);
startActivity(intent);
} else {
// show ERROR
}
}
}
I'm trying to create splash screen without action bar.
Firstly before created splash screen, action bar in main activity and when I create splash screen, action bar comes to splash screen and main activity is full screen. I searched method like getwindow(), getActionBar(), but when I use these method program says to me unfortunately stopped. So what I'm missing?
How can I avoid actionBar in splash screen?
My code:
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash_item);
Thread th=new Thread(){
public void run(){
try {
sleep(4000);
Intent intent=new Intent(MainActivity.this,SplashScreen.class);
startActivity(intent);
} catch (Exception e) {
e.printStackTrace();
}
finally{
finish();
}
}
};
th.start();
}
MANİFEST:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".SplashScreen"
android:label="#string/app_name"
>
<intent-filter>
<action android:name="android.intent.action.SPLASHSCREEN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
First, import the support library in the top of your app:
import android.support.v7.app.ActionBarActivity;
and change your code as follows:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash_item);
getSupportActionBar().hide();
}
Using AppCompat for being supported for all versions:
<activity
android:theme="#style/Theme.AppCompat.Light.NoActionBar">
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
Put that before your setContentView(...), should get the job done.
For Android 3.0 or higher use ActionBarAPI#hide
For lower versions you will need to use Android Support Library.
Use ActionBar as
ActionBar actionBar = getSupportActionBar();
actionBar.hide();
Ref docs
Also if your requirement in static, then you can choose a theme for your activity that dos not have actionbar such as
android:theme="#android:style/Theme.Holo.Light.NoActionBar"
You can do this as:
<activity android:theme="#android:style/Theme.Holo.Light.NoActionBar"
android:name=".name_here"
android:label="#string/app_name" >
use a style without actionbar, also in your splash screen activity java extend Activity and make the splash screen your MAIN activity and in this activity you call an Intent to open your MainActivity after some seconds
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
</activity>
<activity android:theme="#android:style/Theme.Holo.Light.NoActionBar"
android:name=".SplashScreen"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Example:
In your SplashScreen activity write this code. This will open your MainActivity after 2 seconds.
new Handler().postDelayed(new Runnable()
{
public void run()
{
Intent localIntent = new Intent(SplashScreen.this, MainActivity.class);
SplashScreen.this.startActivity(localIntent);
SplashScreen.this.finish();
}
}, 2000L);
This is the simplest method.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
}
where R.layout.activity_main is replaced by your layout activity e.g. activity_splash
I am wondering why my application ignores my SplashScreen.java activity when resuming the aplication. If I close it with the "Back" button, the splash screen comes up on start, but if I exit with the home button the SplashScreen activity is not being called...:(
I even added the onResume event, but the splash screen still wont come up when resuming my app.
Thanks!!
SplashScreen.java
public class Splash extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
spashStart();
}
protected void onResume(){
super.onResume();
spashStart();
}
private void spashStart() {
Thread splashTimer = new Thread() {
public void run(){
try{
sleep(5000);
Intent mainActivity = new Intent("com.exploreca.tourfinder.MainActivity");
startActivity(mainActivity);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
finish();
}
}
};
splashTimer.start();
}

/* just add on resume method inside do not start your splace method in `onResume` method...*/
when you click back button actually the activity is getting finished and when you comes back the splash screen shows. That because once more the appliaction is starting.
When you click home button the activity is not finishing but it goes to background and when you open the app oncemoe then the same activity is bought to front. so the splash screen is not shown.
its how when it works through the lifecycle of the application.
Try to call finish(); method in th onPause of the activity. So it will be finished all the time. Or try adding noHistory to the activity in the manifest. Hope this will help you.
Im very new to android development so please bear my ignorance.
I created a Splash screen before loading my main activity. Splash is working fine but what causes the problem is the main activity, it keeps on instantiating.
Splash.java
public class Splash extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
final AdController optinController = new AdController(
getApplicationContext(), "SECTION_ID");
final Splash splash = this;
optinController.loadOptin((Activity) splash, "SECTION_ID",
new AdOptinListener() {
public void onAdOptin() {
// once optin process is complete, continue to main app activity
launchMain();
}
}
);
}
public void launchMain() {
finish();
Intent myIntent = new Intent(Splash.this, MainActivity.class);
myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivity(myIntent);
}
}
MainActivity.java
public class MainActivity extends Activity {
private AdController myController;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myController = new AdController(getApplicationContext(), "SECTION_ID");
myController.loadNotification();
}
}
In the manifest file:
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".Splash"
android:label="#string/title_activity_splash" >

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
I used android:launchMode="singleInstance" but still it keeps on reinstantiating.
Please help. Thanks in advance.
public class Splash extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);//|Window.FEATURE_INDETERMINATE_PROGRESS
setContentView(R.layout.splash);
final Timer time = new Timer();
time.schedule(new TimerTask() {
#Override
public void run() {
Intent intent = new Intent(Splash.this,MainActivity.class);
startActivity(intent);
finish();
}
},1000);
}}
It will work , i din get you exactly by instatiating.Also do no use single instance,you are not supposed to require it here.
Yes, following is my snippet of manifest file , just use a timer for your splash screen and move to your main class after specific time.
activity android:name=".Splash"
android:screenOrientation="portrait" android:label="#string/app_name">
i think you have to remove the intent flag Intent.FLAG_ACTIVITY_SINGLE_TOP
In manifest.xml, set category as LAUNCHER which activity you want to launch first and to Other set as DEFAULT as given in below example.
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".Splash"
android:label="#string/title_activity_splash" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main"
android:launchMode="singleInstance">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
